The engineering geological conditions of the middle route project of s - n water transfer have been known well and all the involved main engineering geological problems can be solved through engineering measures 对南水北调中线工程的工程地质条件已基本清楚,涉及的主要工程地质问题均可以通过一定的工程措施予以解决。
Therefore the construction process and material properties of rcc arch dam must be simulated precisely so as to take reasonable engineering measures to reduce the thermal stress in the dam 所以,必须准确模拟碾压混凝土拱坝的施工过程和材料特性,仿真计算拱坝温度场和应力场,以便采取合理的工程措施,减少坝体的温度应力。
For the balance , savings would come from reduction in swd expenses , phased reduction of self - care hostel and homes for the aged places , as well as other service rationalization and re - engineering measures 其馀则通过减少社署的开支、分阶段缩减长者宿舍和安老院宿舍宿位,以及实行其他精简服务和重整工作措施来节省开支。
But currently a huge amount of sediment deposited there has caused severe problems and need to be dredged . dredging is one of the effective engineering measures to control floods and improve navigation , irrigation conditions and environment 但是,目前这些河流、湖泊、水库和港口的泥沙淤积严重,需要进行清淤疏浚,以提高防洪、灌溉、通航能力,改善生态环境。
8 disaster factors of soil erosion have been defined : surface material , landform and slope gradient , cover - degree , topographic , 30min rainfall intensity , engineering measure grade of conservation of water - soil , irregular subsidence and volume weight 确定了土壤水性的8个致灾因子: 30而n暴雨强度、地表物质、地形坡度、植被搜盖度、植被类型、工程水土保持措施等级、容重和非均匀沉降
4 . according to sustainable developing theory the research on engineering and non - engineering measures building of disaster decreasing system is taken . it is emphasized on enhancing optimizing allocation of water resources and disaster management 根据可持续发展理论,重点对减灾系统的工程措施、非工程措施建设重点进行了研究,强调了加强水资源优化配置、灾害管理、建立洪灾保险等非工程措施的作用。
Systemic analyses of the practical engineering have been done . the engineering measures including post - pouring belt , part pier pouring with lock floor at one time and pipe cooling is been thoroughly studied . by applying these measures , the stresses in the concrete change 针对实际工程混凝土施工需要,着重研究了后浇带、部分墩墙和底板同时浇筑和布置冷却水管三种工程措施所带来的混凝土应力的变化情况。
On the other hand , we must master the theory of signal analyzing and handling , and the technology of engineering measuring , so we elaborate the basic theory knowledge that we use in the process as theory foundation of building this system 另一方面必须掌握信号分析处理的基本理论和工程测试技术,为此本文阐述了系统开发过程中涉及到的理论知识,作为仪器开发的理论基础。虚拟仪器设计及实现的核心是软件的开发。
Based on the research work about non - negative pressure method of water supply , it was pointed out that there exist some problems in the system if the facilities are not designed or operated properly , and corresponding engineering measure of how to use non - negative pressure method of water supply was proposed 摘要对无负压供水技术进行了分析,指出了设计或使用不合理时可能出现的问题;提出了正确使用无负压供水技术的工程措施。
